Well if I was u, and I have no desire to be u, I would buy a Lotus Elise. There is no better car in the world

That's not a bad idea. Or, for something really special, how about the 0.9L/100km VW XL1? (I wouldn't describe its interior as luxurious, though. And "power" isn't the first word that comes to mind.) If, and that's a big if, other drivers actually see your XL1, they won't take their eyes off it.
